Non-renewable mineral resources

The natural resources of the earth's crust upon which industry depends for metals, non-metallics and most of its energy, come from deposits in the crust carrying six to over 1000 times the normal content of the required elements. Such deposits have formed over such long periods of geological time that they must be regarded as non-renewable within the span of existence of the human species. These facts are briefly illustrated by reference to the cases of iron, copper, aluminium, titanium, magnesium, lead, zinc, flourine and the fossil fuels. The possibilities of exploiting much lower concentrations when considered in relation to the exponential rise in demand, lead to the conclusion that the scope is limited unless very cheap energy becomes available.     

Modelling conflict over natural resources issues

In recent years political instability and economic uncertainty have dominated resources policy issues. As a result, conflicts of interest have arisen in many contexts relating to the control and use of natural resources. A number of methodologies have been developed to study conflict situations in other areas, and this paper seeks to demonstrate the relevance and usefulness of these methodologies in the natural resources field. The resulting models do not always have predictive power but can provide valuable insights into the structure of conflicts.     

Forest resources consumption pattern in Govind Wildlife Sanctuary,Western Himalaya,India

In the present study, forest biomass (fuelwood, leaf fodder, leaf-litter and non-timber forest products) consumption patterns have been evaluated in the villages of Govind Wildlife Sanctuary, Uttarakhand, Western Himalaya, India. The average fuelwood consumption in the selected villages was estimated at 3.14 kg/capita/day and its energy equivalent was found 52.74 MJ/capita/day. The average leaf fodder and leaf-litter consumption was estimated at 2.70 and 2.40 kg/unit/day, respectively, and the same pattern was estimated for energy equivalent. People's perception on impacts of conservation measures and resources utilization rights were also analysed. Our results emphasized the need for regular assessment of forest resources, particularly in protected areas, where access to natural resources have been denied due to legal restrictions. The study could be a pilot to strengthen the conservation measures across the protected area network by understanding the dynamics of anthropocentric activities and their subsequent impacts on forest resources.     

Testing The Pearl Hypothesis: Natural resources and trust

Do natural resources reduce social trust? This paper reviews the literature on natural resources and on trust. The existing theoretical and empirical literature suggests that natural resources can reduce trust through several indirect mechanisms. Notably, studies show that natural resources lead to institutional degradation, corruption, inequality, and civil war, all of which have been associated with reduced trust. In addition, game theoretical work on windfall gains suggests that there may be direct effect of natural resources on trust. This paper tests empirically whether there is a direct effect of natural resources on trust (The Pearl Hypothesis), using cross-country data. The results indicate that no such direct effect exists, but we find a significant effect on trust of intermediate variables affected by natural resources, such as institutions, corruption, inequality and/or civil war. Importantly, the relationship between corruption and trust turns out to be non-linear, indicating that the effect of natural resources on trust depends on the initial corruption level of a country. In highly corrupt societies, institutional improvements that reduce corruption may also undermine trust, which poses difficult challenges for anti-corruption policy.     

Natural resources assessment in the Okavango Delta, Botswana: Case studies of some key resources

This article makes an assessment of the following key natural resources in the Okavango Delta: arable land, basket-making resources, fish stocks, and river reeds. Non-data-intensive socio-economic indicators (as opposed to conventional data-intensive indicators) of trends in resource prices, trends in labour time for resource extraction, substitution of less preferred commodities, maximum sustainable yield and perceived scarcity were utilized to assess the scarcity of the resources. The study reveals that basket-weaving resources, land for flood recession arable (molapo) agriculture, and river reeds are increasingly becoming scarce in the harvesting areas, whereas fish stocks are still abundant. It is recommended that appropriate policies should be introduced for the management of natural resources. Property rights could be granted to communities to manage natural resources such as fish and veld products in line with the wildlife model for community based natural resources management (CBNRM). In addition, the authors suggest that the Government of Botswana should take the responsibility for allocating land for molapo arable farming in order to make it more accessible.     

Environmental policy for sustainable development of natural resources

This paper describes new environmental policies and expanded administrative agencies which in recent years have been adopted by many governments faced with a continuing decline in the quality of their environments. In a number of developed and developing countries, devising a far reaching environmental policy for sustainable development of the natural resources sector is a national priority. Specific environmental policies may be classified according to objectives, timeframe, mechanisms for implementation, whether or not they are binding, and the nature of sanction. This paper provides some generalizations about certain features common to most environmental policies. In the first section an examination is made of some of the most pressing problems which environmental policies relating to natural resources seek to address. The second section discusses environmental policies themselves. The third section, which makes up the main body of the paper, assesses the strengths and weaknesses of a variety of mechanisms available for implementing environmental policies to promote sustainable development in the natural resources sector.     

Optimum cutting age for timber resources with carbon sequestration

Determining the optimum cutting age for timber resources has proved to be a very challenging problem for both economists and silviculturists. Based upon Samuelson's seminal work on this issue, the majority of economists have concluded that the optimum felling age occurs at a time when the net marginal benefits fall below the current rate of interest. Recently, concern about climate change has increased the importance of forestry projects, since trees act as natural biological scrubbers by removing CO₂ from the atmosphere. By incorporating these carbon sequestration benefits, this paper re-determines the optimum cutting age using a multiple rotation model. The results of this reformulation show that, in afforestation projects, trees should remain in the ground longer than the period suggested by a timber-only model in order to absorb more CO₂.     

Natural resources planning, management, and sustainable use in China

Almost all the issues of sustainable development in China relate to natural resources. Sustainable development as one of the most important strategies has been incorporated into all the actions related to the planning and management of natural resources in China. This paper gives an overview of the contributions of natural resources and the challenges facing the natural resource sectors. It contributes a series of proposals on the planning and management of natural resources. It also outlines the general framework of the planning system for natural resources and summarizes the Great Survey of Natural Resources Program that the Ministry of Land and Resources is implementing.     

Cultural values of natural resources among the San people neighbouring Kgalagadi Transfrontier Park,South Africa

Globally, cultural values of natural resources are increasingly recognised as important for local natural resource management and conservation in and beyond parks. The tendency has been to focus on the direct-use rather than the cultural values and importance of natural resources. The cultural values underlying natural resources (directly or indirectly used) and various natural resource-based activities, and the implications for conservation, remain little explored. Drawing from household surveys, in-depth qualitative interviews, observations and secondary data, we explore the cultural significance of natural resources and different land-use practices among the San people bordering Kgalagadi Transfrontier Park in South Africa. Our findings illustrate that though cultural values are inextricably linked to resource use, they are not recognised by all community members. Further, cultural values arise from a diverse and sometimes conflicting array of values that punctuate individuals' lifestyles. A better understanding of context-specific cultural settings and the linkages between the cultural and material dimensions of resource use can lead to the development of interventions that can ensure effective conservation of both natural resources and culture.     

Do natural resources and economic components exhibit differential quantile environmental effects?

In view of the resource curse assumption, the environmental aspects of resource utilization are arguably posing more dangers to human existence. In the Middle East and North Africa (MENA) region, the region that holds more than 60% and 50% of the world's oil and gas reserves respectively, the need to examine the contribution of natural resources to environmental quality among other factors cannot be overemphasized. By leveraging on the novelty of observing the differential impact of natural resources and other economic components such as income and primary energy utilizations across the quantiles of carbon emission, this study implements the quantile regression approach alongside other relevant techniques to analyze data between 1990 and 2018 for selected countries in the MENA region including Saudi Arabia, Iran, Kuwait, Qatar, Algeria, Morocco, Oman, Egypt, and the United Arab Emirates (UAE). The result posits that natural resource utilization generally hampers the environment across the quantiles. However, this negative effect decreases until the 50th quantile before starting to rise again toward the upper quantiles. Additionally, primary energy utilization and globalization respectively worsen and improve environmental quantile, especially toward the upper quantiles while income affirms the inverted U-shaped hypothesis across the entire quantiles. Moreover, there is a statistically significant one-way directional causality from natural resources, economic expansion, primary energy use, and globalization to carbon emission levels. Hence, the study offers environmentally friendly resource utilization policies to the MENA economies and other resource-rich states by extension.     

Surveying and mapping of natural resources by remote sensing

Sustainable economic development requires detailed knowledge of the natural resources of any nation. Acquiring the needed information by conventional means may require a large investment in time, personnel, and therefore, in cost. A viable alternative is space-age technology which provides the necessary tools to conduct surveys of natural resources in a timely manner. Such technologies can obtain the required data by means of digital sensors, radar imaging systems and stereo cameras. These data can be utilized to map structures that may contain oil and gas deposits, recognize high concentrations of economic minerals, and discover regions with fertile soils and good potential for groundwater. Those applications warrant greater use of remote sensing methods and techniques by the international scientific community, particularly for the development of natural resources in the Third World. This paper represents a general review of the available, and easily interpretable, space-borne data that are useful in the mapping of natural resources.     

Scarcity of natural resources and the implications for sustainable development

The idea of sustainable development has much popular appeal, but conflicts with centuries of economic theory about how limited land and natural resources constrain the growth of economies and populations. Much of that doctrine, especially that in the Malthusian tradition, is contradicted by historical experience, but the modern threat of environmental degradation raises new questions about whether growth can be sustained. Many of those new problems result from biases in economic organization and institutions against so-called environmental resources. Marketed resource commodities like minerals and timber are protected by the incentives of owners and suppliers to conserve them, enhance them and find new sources, and by the incentives of users to economize on their demands and find cheaper substitutes. Together, these forces have been sufficient to offset depletion and render resources less scarce over time. The same forces are not at work on environmental resources like water and air, so they are over-used and degraded as demands grow. However, promising opportunities exist to develop property rights and economic incentives to encourage users of environmental resources to protect and husband them, and these are likely to be more effective in harmonizing economic activity with the environment than purely regulatory policies.     

Water resources issues of small island developing states

The water resources of most small island developing states (SIDS) are often very limited and require special consideration to ensure that they are developed and managed in a sustainable manner. Many small islands, typically located in the humid tropics, have no surface water resources and rely on limited groundwater resources in the form of thin freshwater lenses. The exposed location of small islands makes them particularly vulnerable to natural disasters such as cyclones, floods and droughts. Pollution from population centres and from agricultural and other activities is an increasing problem. This article provides an overview of the water resources of small islands, and the main problems and issues related to water resources. Some suggested solutions, based on practical experiences, are offered for water resource assessment and monitoring programmes, and water resource development. Water resource policy, planning and management issues are also addressed, and suggested approaches for resolving some of the major water resource problems presented.     

Issues in natural resources management in developing countries

Recognizing the steady depletion of natural resources in developing countries, this study analyses its causes by focusing on the ownership of such resources. Resource degradation was found associated with an array of individual, socioeconomic, politicoeconomic and institutional factors. In the pursuit of sustainable regional resources management and conservation, it is necessary to analyse and incorporate these multifarious factors into the design of a comprehensive strategy. While local government should be responsible for devising management strategies, their implementation requires the interfacing of field agencies with local communities that are to be assisted in the short term and instructed in depth; their performance should be closely monitored over the long term.     

Valuing natural resources and the implications for land and water management

New models of sustainable development stress the importance of the efficient management of resources, including labour, capital equipment and natural resources. Overuse of the resource base today will lead to shortages tomorrow; yet it can be a difficult task persuading politicians and planners in developing countries of the importance of resource management. This paper suggests methodologies for doing so and argues the urgency of the task.     

Greening the Brazil,Russia, India,China and South Africa (BRICS) economies: Assessing the impact of electricity consumption,natural resources,and renewable energy on environmental footprint

Electricity consumption is a crucial factor in the environmental pollution process, and therefore, its impact needs to be carefully considered by policymakers. This study investigates the relationship between energy consumption, electricity generation, natural resource utilization, and environmental pollution in BRICS nations, which have a substantial share in global resource consumption. To this end, we employed a novel methodology, namely the Method of Moment Quantile Regression (MMQR), for the time period between 1990 and 2018, within the framework of the Environmental Kuznets Curve (EKC) theory. The study's outcome shows that natural resources and renewable energy are efficacious and significant in curbing environmental degradation among the sample countries. The investigation reveals a positive correlation between electricity consumption and environmental degradation, thereby highlighting this vital resource's role in exacerbating the BRICS nations’ ecological footprint. The findings from this research can provide crucial insights for policymakers to achieve sustainable development and carbon neutrality in these countries.     

The hotelling valuation of natural resources: some further results

This paper tests the Hotelling Valuation Principle (HVP) for natural resources using data from oil and gas ‘pure plays’ such as royalty trusts and master limited partnerships. The results support the HVP which specifies that the value of any mineral reserve may be predicted by the market price of the resource, net of extraction costs. Regression results also indicate that a Box-Cox transformation of variables provide a better means of estimating the functional relationship between the value of an exhaustible natural resource and its market price.     

Managing natural resources in the light of climate variability

Natural resource management is central to global efforts to reduce poverty and environmental degradation, and is one of the principal ways in which countries are seeking to advance sustainable development and the implementation of Agenda 21. But these efforts to advance natural resource management are strongly impacted by climate and by seasonal and inter–annual climate variability.
This article aims to further advance understanding of the relationship between natural resource management and climate variability, with particular attention to ways in which natural resource managers at every level — from the household to the national and international levels — can cope more effectively with such variability. In particular, the article provides an overview of the way in which efforts to manage natural resources to reduce poverty and environmental degradation are impacted by natural climate variability. It examines what natural resource managers are doing to cope with these challenges, and discusses the kinds of new approaches and partnerships that are needed to improve their capacity to cope more effectively with climate variability. In doing so, the article touches on the implications of future climate changes for natural resource managers and the way in which their efforts to cope more effectively with climate variability will provide opportunities to gain experience in identifying and adjusting responses to longer–term climate change.     

Toward sustainable use of natural resources: Nexus between resource rents,affluence, energy intensity and carbon emissions in developing and transition economies

Sustainable use of natural resources would entail ensuring that derived economic benefits today do not undermine the welfare of generations to come. On this basis, this study examines the nexus between natural resource rents and carbon dioxide (CO₂) emissions disaggregated into production and consumption-based (i.e., trade-adjusted) CO₂ emissions for a selected panel of 45 developing and transition economies over the period 1995–2017. The empirical model also incorporates the impacts of population, affluence, and energy intensity. The results show that affluence increases production-based CO₂ emissions by 1.407%, with the EKC's predicted inverted U-shaped curve only explaining consumption-based CO₂ emissions. Economic reliance on natural resource rents and energy intensification contribute 0.022% and 0.766%, respectively, to CO₂ emissions embedded in territorial production inventories and 0.035% and 0.583%, respectively, to CO₂ emissions embedded in consumption inventories. The bootstrap non-causality test shows that historical data on each variable has significant predictive power for future CO₂ emissions from both sources. The historical information about natural resource rents has significant predictive power over the future levels of affluence and energy intensity. Clearly, the results show that the environmental impact of natural resource rents is stronger when CO₂ emissions are adjusted for trade and varies among the countries, with Bangladesh, Guinea, India, Malaysia, Mexico, Nigeria, Pakistan, Saudi Arabia, Vietnam, and Zimbabwe among the most affected countries. Overall, this study provides motivation for policies to keep the use of natural resources within sustainable limits.
